This session consist of three sections including an 40Ar/39Ar section:

- 40Ar/39Ar dating: from geochronology to thermochronology, from archaeology to planetary sciences:

The 40Ar/39Ar dating technique is increasingly becoming one of the most trusted dating techniques in the geological community. The 40Ar/39Ar method has been in use since more than 40 years, and has been in constant evolution since then. The steady improvement of the technique is largely due to a better understanding of the K/Ar system (e.g. alteration effects) along with a continuous refinement of the method (e.g. measurement techniques, constants, interpretations). The 40Ar/39Ar method is also one of the most versatile techniques with countless applications in archaeology, tectonics, structural geology, orogeny and provenance studies, ore and petroleum genesis, volcanology, weathering processes and climate, and planetary sciences.

In this session, we welcome all range of contributions about 40Ar/39Ar dating at large with emphasis on methodological developments with original ideas or new concepts, modeling and data handling, and direct applications of the 40Ar/39Ar technique.
